Abstract:This report describes the FHWA Level 1 Highway Traffic Noise Prediction Model. This model is given the acronym "SNAP 1.0" for Simplified Noise Analysis Program 1.0. The model is designed to allow the quick calculation of highway traffic noise emissions for simple roadway-receiver configurations. All computed for traffic lanes parallel to the barrier. Both "thin screen" and "berm" type barriers are considered by the model. Vehicle noise emissions are estimated by vehicle type and vehicle speed.
